Cannot build cffi on Pico Ultra W "/usr/bin/ld: cannot find -lgcc"

Hello,

I'm having troubles installing the "cffi" package as linker fails because of "-lgcc" is not available (package gcc-multilink is not available).

It fails with "/usr/bin/ld: cannot find -lgcc" error.


To reproduce do the following:
* flash clean ubuntu image on pico ultra w board
* install apt packages: python3.10-venv and libffi-dev
* create virtual environment
* activate virtual environment
* execute "pip install cffi"

This is the complete output:

Hello, based on the log you provided, it seems that the corresponding library files are missing. Please try executing the following commands to resolve the issue:

Code: Select all

sudo apt-get install gcc
sudo apt-get install gcc-multilib
When setting up a Python virtual environment, you might need various development tool packages (*-dev). Compiling these packages can be time-consuming. In the future, we plan to introduce a Docker-based rootfs image building method, allowing some of these time-consuming tasks to be executed on a PC.

GCC was installed from the start (as well as the needed *-dev packages).

As I wrote in my question, GCC is missing gcc-multilink package, which is not available in default "ports" repository for ARM.

Can you please provide further info on how to install gcc-multilink package?

Code: Select all

master@pico:~$ sudo apt install gcc-multilib
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package gcc-multilib is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

We haven't conducted related tests, and there are too many Python packages for us to check each one individually. Previously, when I was porting Home Assistant to Alpine, I also encountered issues with installing the cffi dependency. Unfortunately, I didn't document how I resolved it, so I've forgotten the solution. If there's any progress later, I'll inform you immediately.

If it's convenient, could you let me know the project you plan to validate? Perhaps I can suggest a better alternative.

Please try to remember if possible.

Project we're trying to deploy is our internal project.
And cffi is dependency of poetry which we cannot install currently.
Yes, using the plain pip for dependency management is an alternative, but having this also working would be perfect.

No, I try to set up HomeAssistant on luckfox pro max, and can't do nothing. cffi 1.17.1 needed, but default older version. build not possible. How can I resolve this? Thank you.

When porting Home Assistant, I chose not to use Ubuntu as the root filesystem (Ubuntu consumes too many memory resources). Instead, I used armv7l/Alpine in a Docker container on a PC to execute the build, which eventually ran successfully (even though it took a lot of time on the PC). On Ubuntu, I'm unsure how to verify if CFFI is working correctly (I don't have the time to spend significant effort trying to port Home Assistant on Ubuntu again). Therefore, for now, the CFFI issue on Ubuntu will remain a pending task. I will inform you as soon as there is progress.

Thank's for an answer.
Do you have instructions, how to install HA on Alpine ?
And correct way to install alpine on sd card for Luckfox?
I kill a week, to try install gcc with multilab :(
Thank you.
